Flash and Shockwave Forum

A few days ago I asked a freelance designer to design a flash header for an important page of our site. Its done and now online. While checking my Google analytics stats I found almost ten percent of the visitors are using version six. Now how shall I check if the flash presentation is compatible with flash version six/other versions? Are there any tools/wayouts to do some compatibility test?

Please suggest.

[NOTE: I also came to know that there is a flv file that is being called from inside the swf .. also uses streaming using, netstream, netconnection and Video class]
